在程序中如何组装组装数据

在程序中如何组装组装数据

通常我们在写代码的时候当需要一个对象的时候，首先就是new 一个对象

 EcOrderOperateHistory orderOperateHistory = new EcOrderOperateHistory();
        orderOperateHistory.setId(IdWorkerUtilss.getIdStr());
        orderOperateHistory.setOperateMan(operateMan);
        orderOperateHistory.setOrderId(orderId);
        orderOperateHistory.setRemark(remark);
        orderOperateHistory.setOperateDateTime(LocalDateTime.now());`

这样我们会在程序中写大量的set方法，看起来很low
或者我们直接builder一个，如果一个对象的属性过多的话，就显得这行代码过长了

这个时候我们就可以在实体类中写一个组装数据的方法

@Data
@Accessors(chain = true)
public class EcOrderOperateHistory implements Serializable {

    private static final long serialVersionUID = 1589010323280L;
    @Id
    private String id;
    private String orderId;
    private String operateMan;
    @JsonFormat(pattern = DatePattern.NORM_DATETIME_PATTERN, timezone = "GMT+8")
    private LocalDateTime operateDateTime;
    private String orderStatus;
    private String payStatus;
    private String deliveryStatus;
    private String balanceStatus;
    private String remark;
  public static EcOrderOperateHistory assembleOperateData(String orderId, String operateMan, String orderStatus, Integer orderSettlementStatus, String remark) {
        EcOrderOperateHistory orderOperateHistory = new EcOrderOperateHistory();
        orderOperateHistory.setId(IdWorkerUtilss.getIdStr());
        orderOperateHistory.setOperateMan(operateMan);
        orderOperateHistory.setOrderId(orderId);
        orderOperateHistory.setRemark(remark);
        orderOperateHistory.setOperateDateTime(LocalDateTime.now());

这样我们的代码就显得格外的清晰了，调用了这个方法 别人就知道你这是在组装数据
